Given numbers are 620, 221, 127, 971
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(620, 221) = 137020
GCD(620, 221) = ( 620 x 221 ) / 137020
= 620 / 221
= 620
Step2:
LCM(1, 127) = 127
GCD(1, 127) = ( 1 x 127 ) / 127
= 1 / 127
= 1
Step3:
LCM(1, 971) = 971
GCD(1, 971) = ( 1 x 971 ) / 971
= 1 / 971
= 1
So, Greatest Common Divisor of 620, 221, 127, 971 is 1
